periodicity/periodic table

It's all about the apps: EMD PTE

Having completed a unit on stoichiometry,  I was looking to review with my HS students some key topics before Spring Break.  I had received from FLINN scientific their "It's Elementary--March Madness" activity:

Trend Setter Lab

Students will proceed through a pre-lab engagement activity, organize element cards based on similarities & trends, discuss trends with the class and then produce a periodic table that includes the trends discussed within the lab.

Periodic Table Project

Students choose a topic and select items to incorporate into a periodic table. Students explore trends related to their own topic and relate to the trends on the actual Periodic Table of Elements.
